Trigger dependencies and "inherited" templates

[Calimero]

Hi,

I have the follwing template setup:

X_Server --> X_Linux --> X_L_Web --> X_LAMP

I have a host (intranego-dev) linked with template X_LAMP.
It inherits all the triggers and items.

See attached file host_items.PNG for all items.

X_Server: ping (item+trigger)
X_Linux: + ssh (item+trigger)
X_L_Web: + HTTP 80 (item+trigger)
X_LAMP: + MySQL 3306 (item+trigger)

Triggers are all defined with a dependency to the ICMP Ping trigger.

For example HTTP trigger on template X_L_Web has a dependency to "Echec Ping X_L_Web" (= ping failure).

All triggers work fine on host intranego-dev except for one thing: dependencies are not used.
If ping fails and then HTTP/SSH/MySQL fail, I get 4 alerts.

I've created an "HTTPS 443" item and a "HTTPS 443 Down" trigger with a dependency to "Echec Ping intranego-dev". This is local/specific to intranego-dev.
On that very trigger, dependency is checked and I won't get notified if HTTPS fails while ping is already down.

Well, what did I do wrong ?
I created dependencies between triggers of the same level (HTTP trigger on X_L_Web depending on Ping trigger on the same template and not on X_Server). Is this correct or should I "point" to the ping trigger from X_Server ("root" remplate that actually provides the ping trigger) ?

Thanks for your help !
